Sometimes you should and sometimes you shouldn’t, but the border between should and shouldn’t is very complicated. The only way to give a general answer is […]
ReKep: Spatio-Temporal Reasoning of Relational Keypoint Constraints for Robots
Abstract Representing robotic manipulation tasks as constraints that associate the robot and the environment is a promising way to encode desired robot behaviors. However, it remains unclear how to formulate the constraints such that they are 1) versatile to diverse tasks, 2) free of manual labeling, and 3) optimizable by off-the-shelf solvers to produce robot […]
Web Components Are Okay
Every so often, the web development community gets into a tizzy about something, usually web components. I find these fights tiresome, but I also see them as a good opportunity to reach across “the great divide” and try to find common ground rather than another opportunity to dunk on each other. Ryan Carniato started the […]

How Dwarf Works
Introduction Welcome to the series on parsing and using DWARF debug info! Its purpose is to provide a user-friendly starting point for learning about how debug information and debuggers work on Linux. It’s written from the perspective of a debugger author, not a compiler author. Non-goals include being a 100% comprehensive guide, providing details on […]
